The present study aimed to express, purify and identify the major allergen gene, Pla a1, in Platanus pollen. According to previous studies, the major gene sequences of the Pla a1 allergen were obtained and codon optimization and synthesis of the genome were performed using DNAStar software. Following binding of the target gene fragment and the pET-44a vector, the JM109 cells were transfected to...

the efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...

Recent studies have shown that surfactant components, in particular the collectins surfactant protein (SP)-A and -D, modulate the phagocytosis of various pathogens by alveolar macrophages. This interaction might be important not only for the elimination of pathogens but also for the elimination of inhaled allergens and might explain anti-inflammatory effects of SP-A and SP-D in allergic airway ...

Background Allergen-specific immunotherapy (SIT) is the only specific, disease-modifying treatment for allergy and may have long-lasting effects. It is given traditionally in the form of multiple subcutaneous injections which makes the treatment inconvenient. Furthermore, systemic allergenadministration may cause severe side effects. Therefor the development of alternative routes for SIT has be...

Background Classical allergen-specific immunotherapy (SIT), using subcutaneous injections with food extracts, may be effective but dangerous due to anaphylactic side-effects. The FAST project (Food Allergy Specific Immunotherapy) aims at the development of safe and effective treatment of food allergies, targeting persistent and severe allergy to fish (cod) and fruit (peach). Both are caused by ...

Background: During the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. Lactococcus lactis (L. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. Hence, L. lactis is an ideal candidate for mucosal immunotherapy. Profilin (Che a 2), the major allergen in Chenopodium album, is one ...

although food allergy is a major public health problem, currently there is no effective and safe treatment except to avoid the foods .but the need for new options is critical now as the number of children diagnosed with food allergies rises. avoiding the offending allergen in the diet is the primary treatment of food allergy. once a food to which the patient is sensitive has been identified, th...

Parietaria pollen is one of the major causes of allergic reaction in southern Europe, affecting about 30% of all allergic patients in this area. Specific immunotherapy is the only treatment able to modify the natural outcome of the disease by restoring a normal immunity against allergens. The preparation of allergen-solid lipid nanoparticles as delivery vehicles for therapeutic proteins, P. jud...
